Comparison between three static mixers for emulsification in turbulent flow

This paper deals with comparing performances of three different static mixers in terms of pressure drop generated by both single-phase flow and liquid-liquid flow in turbulent flow regime and in terms of emulsification performances. The three motionless mixers compared are the well-known SMX™ and SMV™ and the new version of the SMX called SMXPlus™. This experimental study aims at highlighting the influence of the dispersed phase concentration and some of the geometrical parameters such as number of elements and design of the motionless mixer on droplets size distributions characteristics. Finally, experimental results are correlated in terms of Sauter mean diameter as a function of hydrodynamic dimensionless numbers.
